Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description The issue is related to a side channel information disclosure in the getNeighboringCellInfo function of PhoneInterfaceManager.java. This could allow an app to determine whether another app is installed without requiring query permissions, potentially leading to local information disclosure. No additional execution privileges are needed, and user interaction is not required for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the getNeighboringCellInfo function of PhoneInterfaceManager.java to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
